| 摘 要： | 将荧光性能优异的Eu(acac)3(络合物A)与EDTA双酐掺杂在4,4 二氨基二苯甲烷形成的聚酰亚胺(PI)中制备了发光纳米复合材料.荧光测定结果表明,材料荧光强度随Eu3 掺杂浓度的增加而增大;从透射电镜照片观察到络合物A在含PI溶液中是以粒径介于100～200nm的纳米球存在,而且可以明显看到每个小球都被PI包覆,厚度大约为6nm,形成了核壳结构.

| Abstract: | Photoluminescence nanomaterials containing europium fluorescence complex and PI that show high intensity of fluorescence were prepared.The fluorescence spectra demonstrated that the fluorescence intensity increased with the increase of the contentration of europium complex in the solution.The TEM results indicated that the complex crystallized in the solution including PI and the size of the nanospheres was 100 nm to 200 nm.Moreover,we observed that core-shell structure formed and each nanosphere was packed by PI of a thickness of 6 nm. |
